Objectives

This Curricular Unit aims to develop fundamental skills in measuring quantities and signals of current interest in the various fields of engineering and in conceiving and designing electrical and electronic devices and equipment for measurement and instrumentation.

Thus faced with a problem of measuring an electric or non electric quantity, the student should be able to select, define and evaluate the measurement method, the most appropriate components, equipment, procedures and programs, as well as to design the respective measurement chain or instrumentation system.

Learning outcomes and competences

Learning outcomes in this Curricular Unit are assessed from the capabilities to:

• Explain and analyze operating principles of electronic devices in typical situations of measurement and instrumentation;
• Properly use electronic and virtual instruments in experimental measurements of electrical quantities and signals, recognize and evaluate possible sources of error;
• Apply knowledge on sensors and instruments for measuring non-electrical quantities and signals;
• Interpret the most important specifications of the major components of the measuring chain, in particular conditioning circuitry, analog- digital converters, and transducers of non-electrical quantities;
• Characterize a measurement problem and prepare requirements and technical specifications;
• Conceive, design, implement and validate measurement systems and instrumentation for specific applications;
• Organize and prepare technical documentation related to a method or instrument and apply methods for evaluating the quality of measurement.

In order to achieve the above mentioned aim, students should develop the skills outlined below.

– Specific technical skills:

• Mastery of technical concepts of measurement, instrumentation and use of their technologies;
• Development of reasoning in analyzing and solving measurement problems systematically and accurately;
• Development of design, implementation and test skills of instrumentation for specific applications.

– Other skills:

• Development of skills for experimental team work by performing laboratory and project work;
• Development of written and oral technical communication skills.

Teaching methods and learning activities

– Lectures, in which the theoretical concepts are presented, and application problems are solved and discussed;

– Theoretical-practical classes, with a more experimental character, where theoretical concepts will be applied and laboratory work will be carried out.

Eligibility for exams

– Laboratory classes are mandatory and subject to the regulations regarding the maximum number of allowable absences.

– If students miss an assignment, even if the absence is adequately justified, it does not eliminate it from the count for classification purposes. 

– Students are required to attain a minimum grade of 9.5 in 20 marks in the laboratory work assessment for it to be considered completed.

– Students with approval of laboratory practice (rating greater than 9.5) obtained in previous academic years can maintain this classification. To this end, they must not enroll in laboratory classes, otherwise they cancel definitively the previous laboratory classification.

Calculation formula of final grade

The final grade is the average of two grades, corresponding to the theoretical and laboratory components of the course.

The grades for each of the two components are evaluated as follows:

– Theoretical component  (50%):

• Exam grade = 40%
• Average of written assignments = 10%

– Laboratory component (50%), divided into:

• Average of the 3 best classifications of the 4 laboratory works carried out with evaluation = 30%
• Project evaluation = 15%
• Student participation and assiduity = 5%

Minimum passing grade: 9.5 marks in 20 at each of the two components mentioned above.

Examinations or Special Assignments

– Written assignments are answered individually and consist of solving problems available throughout the semester, at the end of 4 of the main topics taught in theoretical classes.

– Students will be evaluated in practical laboratory classes based on participation and performance in classes, written answers to questions, demonstration and project report (with grading weights as indicated above).

– Special period exams (degree completion or others) follow the rule applicable to regular period exams.

Internship work/project

A project of a complete measurement chain will be assigned in the lab classes.

Special assessment (TE, DA, ...)

Laboratory work is compulsory to all students. Students with a special status may be subject to specific analysis in order to provide attendance in one of the classes with the most appropriate timetable. Nevertheless, they will be assessed just like the other regular students.

Classification improvement

– Of the theoretical component through the completion of the exam at a later appropriate period for that purpose. The written essays component passes to the exam.

– Of the laboratory component by performing all of this component in the following academic year.
